Table 48 Firmware Specifications (continued)
Configuration Backup & | Make a copy of the ZyXEL Device’s configuration. You can put it back on |
Restoration | the ZyXEL Device later if you decide to revert back to an earlier |
| configuration. |
|
|
Network Address | Each computer on your network must have its own unique IP address. Use |
Translation (NAT) | NAT to convert your public IP address(es) to multiple private IP addresses |
| for the computers on your network. |
|
|
Port Forwarding | If you have a server (mail or web server for example) on your network, you |
| can use this feature to let people access it from the Internet. |
|
|
DHCP (Dynamic Host | Use this feature to have the ZyXEL Device assign IP addresses, an IP |
Configuration Protocol) | default gateway and DNS servers to computers on your network. Your |
| device can also act as a surrogate DHCP server (DHCP Relay) where it |
| relays IP address assignment from the actual real DHCP server to the |
| clients. |
|
|
Dynamic DNS Support | With Dynamic DNS (Domain Name System) support, you can use a fixed |
| URL, www.zyxel.com for example, with a dynamic IP address. You must |
| register for this service with a Dynamic DNS service provider. |
|
|
IP Multicast | IP multicast is used to send traffic to a specific group of computers. The |
| ZyXEL Device supports versions 1 and 2 of IGMP (Internet Group |
| Management Protocol) used to join multicast groups (see RFC 2236). |
|
|
Time and Date | Get the current time and date from an external server when you turn on your |
| ZyXEL Device. You can also set the time manually. These dates and times |
| are then used in logs. |
|
|
Logs | Use logs for troubleshooting. |
|
|
Universal Plug and Play | A |
(UPnP) | address and convey its capabilities to other devices on the network. |
|
|
Firewall | Your device has a stateful inspection firewall with DoS (Denial of Service) |
| protection. By default, when the firewall is activated, all incoming traffic from |
| the WAN to the LAN is blocked unless it is initiated from the LAN. |
|
|
IP/MAC Address Filters | Your device’s packet filtering function allows added network security and |
| management. |
|
|
Application Filter | Application filter allows you to block instant messaging programs. |
|
|
URL Filter | URL filter allows you to block access to Internet web sites that contain key |
| words (that you specify) in the URL. |
|
|
QoS (Quality of Service) | You can efficiently manage traffic on your network by reserving bandwidth |
| and giving priority to certain types of traffic and/or to particular computers. |
|
|
Remote Management | This allows you to decide whether a service (HTTP or FTP traffic for |
| example) from a computer on a network (LAN or WAN for example) can |
| access the ZyXEL Device. |
|
|
PPPoE Support | PPPoE |
(RFC2516) | connection. It allows your ISP to use their existing network configuration |
| with newer broadband technologies such as ADSL. The PPPoE driver on |
| your device is transparent to the computers on the LAN, which see only |
| Ethernet and are not aware of PPPoE thus saving you from having to |
| manage PPPoE clients on individual computers. |
|
|
Other PPPoE Features | PPPoE idle time out |
| PPPoE dial on demand |
|
|
Multiple PVC | Your device supports up to 8 Permanent Virtual Circuits (PVCs). |
